So far, no ones to my knowledge has a working set of motorised walking legs attached to their Inmoov robot.
The closest I have seen was by John Stager, His robot legs did walk, but were not stable enough for him to risk attaching his Inmoov robot to
There are other projects to try and make a set of legs that allow an Inmoov to walk.
You can follow the progress of Haracini and myself in his Discord channel is you choose, but it is a long way from complete.
